Just got my new revo 2's... However, I think this is my truck's first alignment ever. I've had it for the last 10k miles. It has just under 40k. The rt front camber/caster adjuster was completely seized. Even after heating it up red hot, using a breaker bar did nothing but BREAK THE SOCKET IN HALF!!! I've never seen that before, but Matco will be replacing my tech's socket. I ordered $30 in parts and after Tuesday, should be fine. The left front is dialed in, but the rt front camber is off .5 degrees. Though my mileage is low, it is a 2006. No rust seen underneath, just seized adjuster. Hope it works out.
